A RESPONSE TO THE ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT REPORT OF THE PROPOSED SODA ASH MINING FACILITY BY LAKE NATRON RESOURCES LTD AT LAKE NATRON, TANZANIA
We, the undersigned, do not believe that the Government of Tanzania should authorize Lake Natron Resources Ltd a company jointly owned by Tata Chemicals and the Tanzania National Development Corporation to establish a soda ash extraction plant at Lake Natron.
Of great importance to us is the presence of 75% of the global population of the Lesser Flamingos, also red listed as threatened species by the 2006 IUCN report. This makes the Lake a tourist destination far and wide and whose ecological value stretches to Kenya and Ethiopia. It also provides the local pastoralist community consisting mainly of the Maasai with water, not only for domestic purposes, but also for their livestock. We are also concerned about the environmental implications of establishing the plant at the lake due to the expected sulphur dioxide emissions into the atmosphere. We therefore urge to Governments of Tanzania and India to shelve the plans to build the soda ash plant at the lake and in so doing, conserve it as part of Tanzania’s heritage.
